Watts are a measurement of power

Answers

Answer 1

Answer:

Watts are a measurement of power, describing the rate at which electricity is being used at a specific moment. For example, a 15-watt LED light bulb draws 15 watts of electricity at any moment when turned on. Watt-hours are a measurement of energy, describing the total amount of electricity used over time.

Please mark as brainliest.

Answer 2

Answer: True

Watts are a measurement of power, used in light bulbs and other electricity. It is also measured as candela (C) in SI Units. The answer to the question is true because of this measurement.

in an experiment it was found that the total charge on an oil
drop was 5.93 X 10^-18 C How many negative charges does
the drop contain? (#51)

Answers

Answer:

37 negative charges.

Explanation:

We're being asked to determine how many negative charges a drop contains from an oil drop experiment where the total charge was 5.93x10-18 C. The drop contains 37 negative charges.

It was stated and identified that we are to attempt question #51 alone.

From the given information;

The total charge on an oil drop = 5.93 × 10⁻¹⁸ C

According to Oil drop experiment carried out by Robert Milliken in (1910);

In the oil drop laboratory experiment, It was possible for Him to substitute oil for water (because water quickly evaporate). Robert Milikan adjusted the electrical voltage among the two metal plates while the oil drop continues to drop until it stopped. When the drop was stopped, the gravitational downward force on the oil drop was equivalent to the electrical upward force on the charges thereby enabling Robert Millikan to be able to estimate the electrical charge drop.

Robert Milliken identified that the magnitude of a single negative electron charge is:

= 1.6 × 10⁻¹⁹ C

If in an experiment, the total charge =  5.93 × 10⁻¹⁸ C

Then;

The number of negative charges in the oil drop can be calculated as;

[tex]\mathbf{=\dfrac{5.93 \times 10^{-18}}{1.6 \times 10^{-19}}}[/tex]

= 37.063 negative charges

Therefore, we can conclude that the numbers of negative charges contained in the total drop = 37.063.

Explanation:

1. A camper named Bob ran into aliens on a trail. Bob made friends with the aliens so he could
steal their treasure of 1 zygot.
1 zygot = 3 trigots
3 trigots = 2 bigots
4 bigots = 1 gram gold
How many grams of gold did Bob take from the aliens?

Answers

Answer : The number of grams of gold Bob take from the aliens will be 0.5.

Explanation :

As we are given that:

1 zygot = 3 trigots

3 trigots = 2 bigots

4 bigots = 1 gram gold

Now we have to determine the number of grams of gold Bob take from the aliens.

The number of grams of gold Bob take from the aliens will be equal to:

[tex]\frac{1\text{ zygot}}{1}\times \frac{3\text{ trigots }}{1\text{ zygot}}\times \frac{2\text{ bigots }}{3\text{ trigots }}\times \frac{2\text{ gram gold}}{4\text{ bigots }}[/tex]

= [tex]\frac{6}{12}[/tex] gram gold

= [tex]\frac{1}{2}[/tex] gram gold

=  0.5 gram gold

Hence, the number of grams of gold Bob take from the aliens will be 0.5.

Answer:

The answers are A. and D.

According to the concept of solubility and properties of ionic compounds, magnesium sulfate and sodium nitrate dissolve in water.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Find the number of moles of iron atoms obtain
from 320kg of iron (3) oxide​

Answers

Answer:

320 kg  of iron(III) oxide contain 4007.76 moles of iron atom.

Explanation:

Given data:

Mass of iron(III) oxide = 320 kg (320000 g)

Number of moles of iron atoms = ?

Solution:

First of all we will calculate the number of moles of iron(III) oxide.

Number of moles = mass/molar mass

Number of moles = 320000 g/ 159.69 g/mol

Number of moles = 2003.88 mol

1 mole of Fe₂O₃ contain 2 moles of iron atom.

2003.88 moles of  Fe₂O₃ contain,

2003.88 ×2 = 4007.76 moles of iron atom.

a. Stableb.
b. Deliquescent
c. Efflorescentd.
d. Hygroscopic

Answers

Answer:

c. Efflorescent

Explanation:

Some hydrated salts, when exposed to the atmosphere, give off part of all of their water of crystallization spontaneously to form a lower dehydrated or anhydrous salt. Such salts are known as efflorescent and the phenomenon is called Efflorescence.

Efflorescence occurs when the hydrate's aqueous vapor pressure is greater than the water vapor's partial pressure in the air. For example, because the vapor pressures of washing soda (Na2CO3·10H2O) and Glauber's salt (Na2SO4·10H2O) normally exceed that of the water vapor in the atmosphere, these salts effloresce (i.e., lose all or part of their water of hydration), and their surfaces assume a powdery appearance.
